    238cc Tillotson race motor build

    I’ve been putting off building this because I’ve been waiting on a head from a guy that I’m pretty sure has screwed me out of my $650 that I paid him six months ago. I’m trying to resolve that situation one more time, but I’ve decided to move on with the build since my daughter had to race with...

    Why good chain guards are a good idea

    Today we had the first test nd tune at one of our local tracks. Overall it was a very good day, my dad is going to drive mine this year, and I’m going to step into a more supportive role running one of our local tracks. It was really fun to watch my dad settle in and get fast. My daughter has...

    Really good video on selecting a cam

    Found this on YouTube. This guy knows what he’s talking about, and explains it in a way that most people can understand so I thought i’d share it.

    Flow numbers for the predator

    I got a message today about 4pm that really brightened my day. The new head for my predator is done and has been tested on the flow bench. The numbers on the left are lift, the numbers on the right are the cfm at that lift. This one should bring the thunder.

    My first hemi port job

    I had an extra hemi head, so I decided to experiment a little with it on the dingo motor. I’ve also been working on a GX399 carb that I’ve been working on that’s also going to be an experiment. I got the intake ported on my lunch break today, and I can get my whole index finger through the port...

    30 series upgrades?

    So I’ve been looking at 30 series torque converters for my dingo project, and since I don’t know crap about them, I need some advice. I want to up the engagement as much as possible since I’ve decided to put one of my open motors on this thing. The more the merrier, how high can I make this come...

    Revamping a Roebuck (Dingo?)

    A friend of mine told me a while back that he had an old go kart that he’d give me if I wanted it, and of course I said yes without even looking at it. We finally got together today, and I picked it and another one for parts. I thought it was a dingo judging by the description, but when I got...

    Hooning with the ‘hood

    We had a somewhat nice day today, and I got the bbq grill fired up. While I was waiting for things to smoke we got the go karts out and started playing in the side yard ( not easily visible from the road ) we played chase and drifted in circles, and it wasn’t long before the neighbors started...

    Check out my new billet valve cover

    I had the time bomb logo laser engraved because at the level we run them at they are complete time bombs. You stay on the maintenance to try to prevent it, but sooner or later something in it will become shrapnel. It’s like a time bomb without a visible clock, lol.

    Stock predator on nitro I’m building a new motor for my daughters kart and was setting up the carburetor for 15% nitro since that’s what I run in mine and it’s easier not to have to carry three fuel jugs to the track. It impressed me so much on the stock motor that I made a video about it.

    222cc predator build

    I’m building an open motor for one of my best friends, it’ll be stroked .080 and have a 2.795 bore making it a 222cc. We’re purposely pushing the envelope with this one as it’ll be on 25% nitromethane and 75% methanol to see if the block will take that kind of cylinder pressure. Specs are .040...

    More goodies from Tillotson

    So there was a dad at our track raising Cain because the boys have been running predators which are technically illegal, but these are stock harbor freight predators that I clearanced for racing. They’re running $1200 pro built motors, and I can’t afford that, much less X2 so I did what seemed...

    Got my new block today :)

    My new Tillotson block came in today. I’ve been on a waiting list for months, but it was worth the wait. This is a nice piece. 2.835 bore and factory reinforced. This one is going to go WOOPOW.

    28mm alcohol flat slide on a Briggs for under $100 So the tillotson on my Briggs was garbage so I needed a new carb. I got a 28mm pwk flat slide on amazon for $28, made an intake for $4, and spent $47 at my local motorcycle shop for a throttle cable, air filter, and clamps. I’m still learning how to edit video, so...

    Cheapest race kart bodies

    I know there aren’t a whole lot of racers on here, but maybe someone can help me out. I’m needing two race kart bodies and I don’t want fiberglass, and I’m looking for the best deal I can get on two abs bodies shipped to 72601. Thanks in advance for any help.

    A good friend just gave me this to play with. He still had my dyno that I left with him when I moved to Florida, so it looks like I’m going racing again.
